T all whom it may concern:

Be it known that I, VERNON F. PAVEY, a citizen of the United States,residing at Leesburg, in the county of Highland and State of Ohio, haveinvented certain new and useful Improvements in Corn-Planters, of whichthe following is a specification.

My invention relates to improvements in corn planters and has for itsespecial object the provision of seed feeding devices. These devices areadapted to be operated by the r0- tation of the drive wheel,intermittently as desired, and are mounted upon the planter frame atappropriate points to be thus actuated.

The invention includes especially a seed disk with seed openings thereinarranged to drop the corn edgewise; devices are providedfor determiningat will the number of grains which may be dropped at one time;intermittently reciprocating devices are provided for actuating the seeddisk through the desired angle and for checking the same; further,devices are provided for forcing the 1 grain out through the openings inthe seed disk at the appropriate time. These and other features arehereinafter specifically set forthand their combinations are included inthe claims.

I have not deemed it essential to show a complete corn planter, inasmuchas it will be understood by those skilled in the art how these devicesare applicable to a corn planter and how they are operated; further,

detailed constructions are also shown in my pending application, SerialNumber 411,516, filed Jan. 18, 1908, from which the present application.is divided, and to which reference is hereby made for further detailsof construction and operation.

In the drawings which are hereto attached and hereby made a part of thisspecification, Figure 1 is a side elevation of the seed feeding deviceand the means of operating the same; Fig. 2 is a plan view of the seeddisk and the actuating means therefor; Fig. 3 is a sectional elevationof the seed feeding devices; Fig. 1 shows the slide for determining thenumber of grains which may be dropped at one time; it also includes thegrain ejectors; Fig. 5 is a section through the seed disk along thediameter thereof; Fig. 6 is a detail of the seed ejector.

In the drawings in which the same numeral indicates the same partthroughout, 1

is one of the Wheels of the corn planter supporting the planter frame 2,said wheel having arranged circumferentially thereon the lugs 3 adaptedto engage with the tripping device 1 carried upon the axle 5 and adaptedto be positioned at the appropriate lug 3 by means of a constructionwhich is sufficiently described in the parent application. The trippingdevice 4 is adapted to engage the end of the bell crank 6, pivotallymount-- ed at 7 upon the planter frame 2, and having the arms 8 and 9thereon; the arm 9 has the spring 10 connected thereto, said springbeing secured upon the planter frame 2 at ll, the function thereof beingto return the arm 9 to normal position after the same has been actuatedforwardly by the tripping device i.

The seed box is shown at 12 mounted upon the planter frame, and a furrowopener 13 is carried thereon, supported thereon by means of the metallichanger 14: secured at 15 upon the frame 2, and also by the hook rod 16.At its rear portion the furrow opener carries a seed dropping tube 17which has mounted near its lower opening a valve 18, which is adapted tobe manipulated by the rod 19 connected at its upper end to the arm 8 ofthe bell crank lever 6. It is seen that the valve 18 will be opened bythe operation of the tripping device 4, the spring 10 acting to returnthe valves to a closed position by the pull it exercises upon the arm 9.The position of the bell crank lever 6 and the rod 19 and the valve 18when actuated by the'tripping device 4 is shown in dotted lines in Fig.1.

Connected to the end of the arm 9, is the actuating plate 20, providedwith the two arms 21 and 22; the latter is bent vertically as shown at23, and has an opening 2 1 formed adjacent to its end through which theappropriate number of seeds may pass as will be hereinafter specificallyset forth. The other arm 21 carries thereon a pivoted finger 25 againstwhich the spring 26 acts to give the same an inward inclination, thelimits of lateral movement of the finger being determined by the flanges27 and 28 formed on the opposite sides of the arm 21. The purpose ofthis finger will be hereinafter set forth. The position of the actuatingplate 20 when actuated bythe dropping device 4 is shown in dotted linesin Fig. 2.

Referring to Fig. 8, the seed box 12 is seen to have a hopper form atits bottom as shown at 29, and in this hopper portion is mounted anirregularly shaped cover plate 30, so constructed that the seed in thebox 12 will converge at the bottom, and will be directed into the openportion 31. Mounted on the short vertical shaft 32 on the planter frame2 to rotate in a horizontal plane thereon is the seed disk 33 providedwith the radial rows of perforations 34 arranged circumferentially. InFig. 2, the seed disk is shown with four openings in each radial row,while in Fig. 4 alternate rows are shown with three openings in each;the openings are so arranged that the grain of corn will passtherethrough edgewise. The provision for dropping the grains edgewisehas advantages over other forms of construction which are apparent tofarmers and others skilled in the use of corn planters and incultivation of grain, and need not therefore be further described.

The actuation of the disk 33 and the dropping of the seed therethroughis accomplished as follows: The actuating plate 20 being actuated by thedropping device as above described, the finger 25 is moved forwardly asshown in dotted lines in Fig. 2, and engages one of the teeth 35,thereby rotating the disk 33 through a short angle. The distance ofrotation must be sufiicientto bring a new row of openings 34 above theperforated slide 24. It is seen that the contact face of the teeth 35 isbeveled, and the contact end of the finger 25 is also beveled,

- so that when these points are in engage ment they resist a tendency onthe part of the finger 25 to slide laterally and be released fromengagement with the tooth. This tendency to lateral movement on the partof the finger 25 is due to the pressure thereon of the succeeding tooth,which bears against the finger as shown at 36 in Fig. 2. The end of thefinger being in engagement with the face of the tooth 35, and thefollowing tooth 36 being also in engagement with the finger, and slideresistance to the further rotation of the disk is set up, which checksthe movement of the disk and thereby prevents a tendency thereof tooverthrow, or pass too far for the proper delivery of the charge ofgrain through the disk on to the plate 22.

Plate 22 is provided with the opening 24, and the plate is adapted to bereciprocated through an opening 37, formed in the upper end of the seedtube 17, and when in its normal position, the charge delivered throughthe disk into the chamber 38 will pass through the opening 24 and dropdown through the tube 17 upon the valve 18. In the position of the slide22 shown in Fig. 2, in the dotted lines, the seed is delivered into thechamber 38, and when the slideis retracted by the spring 10, to theposition shownin Fig. 3, the seed is free to pass downwardly to thevalve 18. The operation of the seed disk and plate 22 and valve 18 isappropriately timed to accomplish the desired result.

The cover 30, as shown in Fig. 3, carries the seed ejectors 39 pressedupon by the springs 40, and positioned so as to enter the seed openingsin the disk 33 when the said openings are brought to the proper point inthe rotation of the disk. The action of the spring 40 is by expansion,and the tendency constantly is to force the ejectors clownwardly. Theseed enters the openings when the disk is exposed to the grain throughthe opening in the cover at 31, the formation of the seed box in itslower part being such as to direct the movement of the grain toward thispoint, as explained above. As the disk is rotated, the grain is broughtinto proper position to be engaged by the seed ejectors 39, the latterbeing in sliding contact with the face of the disk 33, and properlyspaced to enter the seed openings therein.

hen the disk is being actuated by the finger 25, the plate 22 is movedinwardly to such an extent that the opening 24 therein is out ofregister with the seed tube 17, and consequently no seed can pass atthis time; upon the return of the plate 20, however, to its normalposition, the registration is again effected, and the seed may bedelivered to the lower end of the tube 17.

Under some conditions it is desirable to limit the number of grainsforming the charge, and for this purpose I have shown in Fig. 4 asliding plate 41 which is stepped adjacent to one end thereof, and isactuated by the bell crank 42 pivoted at 43, and slot ted at one end 44to receive a lug or bolt 45 carried on the slide 41. At the other end ofthe bell crank 42 is attached a rod 46 which is actuated with anappropriate lever (not shown), in easy reach of the operator, in a wellunderstood manner. The plate 41 shown in Fig. 4 is so constructed thatone of the seed openings in the disk 33 may be ob structed, or two, orthree; the conditions usually found, however, would not require theobstruction of more than two of the openings, and generally not morethan one would be out of use.

teference is hereby made to the above mentioned parent application forother features of the construction connected with the features hereinset out, it not being deemed essential to embody them in this divisionalapplication; the features herein described relate especially to the seedfeeding devices and means of operating the same.

hat I claim is:

1. In a seed planter a seed receptacle, a disk rotatably mountedadjacent the lower end of said receptacle having a series ofperforations therethrough arranged radially therein and adapted toreceive the grain edgewise from said receptacle in said perforations,projections arranged upon the circumference of said disk, a bifurcatedmember mounted adjacent said seed receptacle, means for actuating saidmember to move one arm thereon in engagement with said disk to rotatethe same and to move the other arm of said member into position toprevent the passage of grain through said perforations during saidrotation of said disk.

2. In a seed planter a seed receptacle, a disk rotatably mounted in thelower portion of said receptacle and having a series of radialperforations therethrough adapted to receive the grain from saidreceptacle edgewise, projections upon the circumference of said disk, abifurcated member mounted adjacent said disk and having one arm adaptedto engage said projection at predetermined intervals to rotate saiddisk, and having a second arm provided with an opening therethrough forreceiving the grain passing through said radial perforations.
